Kananaskis

Cooler temperatures will move into the region on the weekend. Watch for reverse loading patterns with the northern winds and fresh windslabs overlying the melt freeze crust that developed earlier this week. Good skiing can be found in sheltered north areas.

A sz 2 windslab was observed out of steep extreme terrain on the south face of Mt Smuts. The slab was 20-30cm deep, 40m wide and ran 300m. It looks to have initiated near the peak in 40+deg terrain.

3-8cm of snow fell on Thursday that is now overlying thin crust on mainly solar aspects up to at least 2400m. Field observations on Friday were on more solar aspects so teams do not quite have a handle on the height of this layer.

Isolated windslabs are being found in alpine areas along ridglines and in gullied terrain. No reactivity was noted on these slabs on Friday and the ones that were encountered were not that large in size. Previously developed windslabs were observed but were stubborn to trigger. Forecasters still avoided unsupported slopes where the slabs were encountered and choose to ski on more supported pieces of terrain where there was wind affect.

There is a chance of another few cms of snow overnight on Saturday as temperature continue to cool and winds shift to more northerly. Continue to watch for windslabs in alpine and treeline areas.
